PNEUMATIC DUST-COLLECTOR.

Specification of Letters Patent.

Patented Dec. 22,v 191 1.

Application filed April 28, 1913. Serial No. 763,978.

To all whom it may concern:

Be itknown that I, Josnrrr J. SMITH, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Pneumatic Dust-Collectors, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

This invention has reference to improvements in pneumatic dust collectors for the strippers of carding engines. 1

One object of the invention is to provide a simple and efficient pneumatic dust collector for the stripping devices of fiber carding engines which is adapted to be moved from one carding engine to another and is adapted to be driven from the carding engine.

Other objects of the invention will appear from the following description.

The invention consists in such novel features of construction and combination of parts as shall hereinafter be described and pointed out in the claims.

Figure 1, represents a view in elevation of the improved pneumatic dust collector parts thereof being broken away. Fig. 2, represents a sectional view of the same taken on line 22 Fig. 1.

Similar characters of reference designate corresponding parts I throughout.

in carrying this invention into practice, in its preferred form, 1 construct the casing 5 having the ends 6, 6 and the mouth 7 and furnished with the extension 8 having the fan chamber 9 furnished with'the outlet 10 to which is attached. the dust and fiber receiving bag 11 usually of comparatively loose mesh textile material. In bearings of the casing ends 6, 6 is journaled the brush shaft having the pulleys 13, 13 and 14 and the stripping brush 15. The fan chamher 9 has the rotatable shaft 16 furnished with the fan 17 and the pulley 18 which latter is driven by the belt 19 operating over the pulley 14!: of brush shaft 12 and guided by the guide pulleys 20, 20 mounted on the member 21 of casing 5.

In operation casing 5 is adapted to be placed on and sustained by the frame of the carding engine to be stripped with brush 1 5 in contact with the doffingroll of the carding engine and the pulleys 13, 13 are operated by belts in any well known man ner from pulleys appertaining to the card-- 111g engine. During the operation the cot ton or other fiber is taken from the doffer roll of the carding engine by the brush 15 while the fan 17 operated by belt 19 directly from the pulley 14: of the brush roll shaft, draws in air and the dust arising from said stripping operation and delivers said air and dust through the outlet 10 to the bag 11.

This device may readily be moved by hand from one carding engine to another and is efficient in collecting dust arising from the card stripping operation which dust, under ordinary conditions, would pass to the atmosphere and be breathed in by the operatives.

Having thus described my invention I claim as new and desire to secure by Letters Patent.

1. A dust collector of the nature described comprising a longitudinal brush casing having at one side a mouth and provided with aradially extending fan chamher, a fan having a shaft journaled at the axis of said fan chamber and having exteriorly of said chamber, a pulley, a dust receptacle sustained by said fan chamber, a brush having a shaft journaled in the ends of said brush casing and having at one end a pulley, a belt operating on said respective pulleys, and means for guiding said belt intermediate said pulleys. I

A. dust collector of the nature de scribed comprising a casing having a longitudinal mouth and an outlet located at a point intermediate the length of said casing copies of. this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
